Crate srsa

A crate that uses the already well established rsa and pkcs8 crates to provide a simple plug and play experience.

Usage

Saving key pairs

use srsa::Keys;
use anyhow::Result as AnyResult;

fn main() -> AnyResult<()> {
    // The values passed in will be the file names of the private and public keys.
    let keys = Keys::new("priv", "pub");

    // Saves the key pairs to a folder in the cwd called keys and encrypts the private key with a
    // password
    keys.write_to_disk("password", "keys")?;

    Ok(())
}

Using an existing key pair

use srsa::Keys;
use anyhow::Result as AnyResult;

fn main() -> AnyResult<()> {
    let keys = Keys::retrieve_keys("keys/test_priv", "1234", "keys/test_pub")?;
    let ciphertext = keys.seal(b"hi")?;
    let plaintext = keys.unseal(&ciphertext)?;
    Ok(())
}

Encrypting and decrypt things work very similarly.

1. You retrieve the neccessary keys to do the job.
2. You run the appropriate function. The encryption function called seal, the decryption function is called unseal.

Modules

errors

A few error conversions into a custom error type.

Structs

Keys

Contains the key pairs and their names. This struct is to use the key pairs and to retrieve them. It can also be used to create new key pairs.
